Pro Sportfisher Ultra Sonic Discs

Pro Sportfisher Ultra Sonic Disc is the world's first vented brass disc. The Ultra Sonic Disc combines a little weight for the fly with vibrant, solid colors and improved mobility. Discs smaller than 7mm have very little effect, so we decided to start the diameters at 7mm, increasing in 2mm increments up to 11mm for the biggest tube flies.

The Pro Ultra Sonic Disc shape is optimized to create a vortex around the fly, allowing soft modern materials to swim freely instead of collapsing in hard current. The venting holes allow for an easier lift-off for a new cast.
